Propagation of Sense Signals in Large-Scale Magnetic Thin Film Memories

A dynamic analysis has been made of the behavior of sense signals in large-scale magnetic thin film memories. The timed effects of attenuation, distortion, cross coupling and interconnection are superimposed on the transmitted waveforms. The computed signals can be used as a design guide to determine the length of sense lines, the number of intersecting word lines, the sense amplifier requirements, etc. The key limiting factors are the resistance of lines and the capacitance at the line intersections. Design criteria are discussed.
